Sleep Duration, Sleep Apnea, and Gray Matter Volume

Journal of Geriatric Psychiatry and Neurology, 2021
This study aimed to evaluate the effect of sleep duration on brain structures in the presence versus absence of sleep apnea in middle-aged and older individuals. The study investigated a population-based sample of 2,560 individuals, aged 49-80 years. The presence of sleep apnea and self-reported sleep duration were examined in relation to gray matter ...

Neck Circumference and Cerebral Gray Matter Volume

Alzheimer Disease & Associated Disorders, 2020
Background: While obesity is linked with brain atrophy and dementia incidence, associations with regional adiposity are uncertain. Our goal was to determine whether cerebral gray matter volume is related to neck circumference (NC), a measure of regional adiposity having unique relationships with metabolic disorders and ...

Gray matter volume differences and the effects of smoking on gray matter in schizophrenia

Schizophrenia Research, 2007
Many studies have evaluated differences in gray matter volume in schizophrenia, but have not considered the possible effects of smoking, which is extraordinarily common in people with the illness. The present study used voxel-based morphometry (VBM) to examine differences in gray matter in subjects with schizophrenia and evaluate the effects of smoking

Widespread Cerebral Gray Matter Volume Deficits in Schizophrenia

Archives of General Psychiatry, 1992
Magnetic resonance imaging was used to investigate whether the structural brain differences commonly observed in patients with schizophrenia as compared with normal control subjects are specific to gray or white matter, and furthermore whether such abnormalities are localizable to circumscribed cortical regions. Accordingly, 22 patients meeting DSM-III-

Hypothalamic gray matter volume loss in hypnic headache

Annals of Neurology, 2010
AbstractObjectiveHypnic headache (HH) is a rare primary headache disorder characterized by strictly nocturnal headache attacks that mostly occur at the same time at night. The pathophysiology of this disease is poorly understood, but hypothalamic involvement was suspected as the hypothalamus represents the cerebral management center of sleep regulation

Decreased regional cortical gray matter volume in schizophrenia

American Journal of Psychiatry, 1994
The authors hypothesized that cortical gray matter volume reduction in schizophrenia is greatest in the heteromodal association cortex. This area comprises a highly integrated, reciprocally interconnected system that coordinates higher order cortical functions.Total brain and regional gray matter volumes were calculated in 46 schizophrenic patients and

Volume Changes in Gray Matter in Patients With Schizophrenia

American Journal of Psychiatry, 2002
Schizophrenia is generally characterized by a progressive decline in functioning. Although structural brain abnormalities, particularly decrements in gray matter volume, are considered important to the pathology of schizophrenia, it is not resolved whether the brain abnormalities become more prominent over time.Magnetic resonance brain images from 159 ...

Abnormal gray matter and white matter volume in ‘Internet gaming addicts’

Addictive Behaviors, 2015
Internet gaming addiction (IGA) is usually defined as the inability of an individual to control his/her use of the Internet with serious negative consequences. It is becoming a prevalent mental health concern around the world. To understand whether Internet gaming addiction contributes to cerebral structural changes, the present study examined the ...
